Abstract

L'invention concerne un procédé de protection dun message ou dun document. Le procédé consiste à chiffrer le message (P) en utilisant une première clé (a) associée à une première partie (Alice) ; envoyer le message chiffré à une seconde partie (Bob) ; chiffrer le message en utilisant une seconde clé (b) associée à la seconde partie, de sorte qu'il soit chiffré avec les deux clés (a+b) simultanément ; envoyer le message chiffré (a+b) à la première partie (Alice) ; déchiffrer le message en utilisant la première clé (a) ; envoyer le message à la seconde partie (Bob), le message étant chiffré avec la seconde clé (b) ; et utiliser la seconde clé (b) pour déchiffrer le message chiffré, présentant de ce fait le message d'origine P.
